1988 420 SEL brake activation shorts out instument's

If anybody has experience with this I would appreciate advice.
When I hit the brake pedal on my 88 420 SEL the fuel,temp,pressure,speedo,tach, etc.. all go to zero until you release brake pedal then all go back to normal. There is a slight hum when the brake pedal is hit kind of like a resistor noise.
the brake lights don't light either when this happens.
this problem is intermittent, everything works normal then all of a sudden the problem occurs.
